Description
Technical field
The present invention relates to a kind of Multi-station sapphire single-wire swinging cutting machine, specifically by diamond wire saw sapphire crystal and other superhard materials, belong to sapphire special cutting device technical field.
Background technology
The Mohs' hardness of sapphire monocrystal is 9, and its hardness is only second to diamond, so mostly is for a long time cut with the circular saw bit being coated with diamond particles.In order to obtain good surface quality, sapphire monocrystal also adopts the interior round type blade that is coated with diamond particles and scroll saw to cut.Simultaneously the thickness of circular saw bit the thinnest also at more than 1mm, add man-hour sapphire monocrystal waste of material serious.And the saw kerf of diamond fretsaw is only 0.2-0.4mm, so adopt diamond fretsaw to reduce waste of raw materials.
At present, along with greatly developing of electroplating technology and resin-diamond scroll saw, the quality of diamond fretsaw obtains raising at full speed, and price has also dropped to original 20%.Its cutting cost is lower than traditional mortar free type cutting mode, and traditional mortar cutting technique bad environments, not environmentally, and a large amount of mortars needs recycling, consumes a large amount of manpower and financial resources.And the technique of diamond fretsaw cutting need not use mortar, only need to provide water or water base cooling cleaning solution just passable, really achieve environmental protection and produce.
So adopt diamond fretsaw to come alternative traditional saw blade or saw band cutting sapphire, become a kind of trend.But because the machining accuracy of diamond wire saw equipment requires high, and need the support of high-grade AC servo NC system, cause diamond fretsaw production cost expensive.The market of China 95% occupied by the diamond fretsaw cutting equipment of current American-European countries, limits the development of China domestic diamond fretsaw cutting equipment, develops the good diamond fretsaw cutting equipment of cost performance to particularly important us.
It is not very good that situation about using at home sawed by the single line of American-European countries, being mainly reflected in retractable cable wheel diameter too small, causing diamond wire mutually to extrude when moving back and forth at high speed, cause diamond particles to come off, and cutting power declines.A big chunk diamond particles does not play dissection and comes off with regard to oneself extruding, and do not reach the cutting power that diamond wire manufacturer declares, make cutting line amount greatly increase, cutting cost can be in any more at all.Equally, in the cutting equipment of single workbench, in order to cut a workpiece, also need to move back and forth, its number of rounds is also no less than the cutting equipment of multiplex's station, such as: just in time can cut 1 workpiece with 100 rice noodles, needs to cut 300 times back and forth; Cut 3 workpiece with 300 rice noodles, then only need to cut 100 times back and forth.Because the rice number through line cut required for each workpiece is consistent, the single workpiece of above-mentioned cutting needs 30000 meters through line, needs to cut 300 times back and forth do circulation with 100 rice noodles, and circulating with 300 rice noodles only needs to cut 100 times back and forth.
In sum, diamond wire mutually extrudes when moving back and forth at high speed and diamond particles is come off cutting power is declined, and cycle-index is more, damages larger, and adopts multiplex's station cutting scheme simultaneously, can reduce line amount of using, greatly alleviate cutting cost.
